DETECTION OF THE OPERATION OF A MICROWAVE OVEN BY SCANNING MEDIUM NOISE PATTERN

摘要

A new type of measurement (150) recently adopted in the IEEE 802.11 wireless LAN standard is used by the a system and method that allows devices (301) to detect if microwave ovens (302) are operating in their vicinity. By scanning the medium, the devices (301) derive information about whether a commercial and/or residential microwave oven causes interference on the medium (310). The information is derived from the collected pattern of medium occupancy times that is characteristic of microwave ovens by using medium sensing histograms (150) defined by the standard.
